i see what you mean even though I didn't read the whole thing (I multitask with a child and chores at home so I had to speedread)
yes, if a deaf person is obsess with another deaf's hearing status, instead of determine if he is culturally deaf by his action and attitude, yes, that audism too. Because I don't know why they would care how hearing they are. Unless they feel they wouldn't understand where they are coming from because they have exposure to hearing world.
